54 minutes to atmospheric entry.
Wayne Lee says that at 7:47 polling of subsystems will happen to confirm that turn to entry has completed.
Additional info from Steve Squyres, the principal investigator for the Mars Exploration Rovers' science packages: It will probably be about a week and a half before the rover rolls into action. Between landing and then, we'll be "taking a look around" with the rover cameras and picking target rocks. The cameras on this vehicle are 3.5 times the resolution of previous surface pictures, giving the rover much better "eyesight" to pick our targets and drive directions.
